SHEET-METAL-CUTTING PRESS.l

SPECIFICATION forming part of Letters Patent No. 326,183, abad eptember 15, 1885.

Application filed April s, 1,894. (No model.)

To all whom t may concern,.-

Be it known that I, WILLIAM WERTs, a

citizen of the United States. residing at Camden, in the county of Camden and State of New Jersey, have invented a new and useful Improvement in Double-Acting Sheet-Metal Presses, of whicll the following is a specification.

The object of my invention is the cutting embodies the combination of a sinlilar beam,V

arranged above the first-mentioned beam, and provided with punches centrally arranged with the upper dies, with the said revolving eccentrics thereon and connecting-rods,where by to punch the blanks througll central openings ofthe lower dies, as hereinafter fully described. My invention further consists in the combination of vertical eyebolts with the said beams and the upper end of the connecting-rods, constructed as hereinafter described,

the bolts being provided with nuts above and below the beams for the adjustment of the upper dies and punclles.

ln the accompanying drawings, which malte a part of this specification, Figure l is a rear view of my improved press. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view of the die-plate F, on an enlarged scale, provided with the lower dies, G. Fig. 4, Sheet 8, is a vertical section taken through the center of the upper and lower dies, G G, showing a side elevation of the lower end of the punch I, and a blank, L, between the dies. Fig. 5l is a like view of the dies and punch, showing the punch as having descended into the lower die and forming the cup M therein.

Like letters of referencein all the figures indicate the sanle parts.

A is the die-plate of the lower dies, its end being bolted fast to the ilanges a a of' the housings B B.

O is a revolving shaft having gear wheels D D on its end, which connect with the pinions E on the driving-shaft C', which connects with the motive power in any desirable way.

lIn Fig. 2 the pinion on the far end of the shaft is hidden from view by the pinion on the near end. The lower dies, G, are bolted fast to the plate A, and arranged in two or more rows, with the dies of one row alternating with the dies of the adjoining row or rows, in the irlanner shown in the enlarged view, Fig. 3, by which arrangement there is the least waste of material.

H is a beam provided on its lower side with upper dies, G, and H a similar beam provided with punches I, centrally arranged with the upper dies. rlhe vertical arrangelnent of the lower and upper dies and punches in relation to each other is seen in thc enlarged sectional view, Fig. 4, in which a single nest is shown.

The beam H, to the lower side of which the upper dies, G, are bolted, being arranged vertically with the series of lower dies, G, has a vertical reciprocating movement inlparted to 4 it by means of the eccentrics J J, on the ends of the revolvillg shaft C, and their connectingrods K K, and the beam H, to which the punches I are connected, has its movements by means of the eccentrics J J, on the saule shaft, and the eccentric-rods K K.

The upper ends of each pair of rods have a joint-connection with the beams H and H, by means of the eyebolts c and pins d, whereby a free movement is effected in all the varying positions of the connecting rods during the revolutiolls of the shaft C. rI`he eyebolts c are provided with nuts e and jam nuts e at the lower and upper sides of the beams, whereby the vertical adjustment of the upper dies, G, and punches I is effected.

L is the blank (shown in Fig. 4) cut from a sheet of metal preparatory to forming the cup M. l

M is the cup, formed from the blank L by the downward action of the punch I, carrying `the blank through the central orifice of the lower die, G, and dragging up the sheetV on its circumference to form the cylinder of said cnp.

IOO

The ecccutrics J J and J J are so a1'- ranged that when the beam H is at its lower position the beam H Will be at its higher position, so that when the upper dies shall have by their pressure in the lower dies formed the blanks L the punches commence their downward movement for discharging the blanks.

For' giving the finishing form to the blanks L, the dies G and G are removed from the dieplate F and beam H, respectively, and the forming-dies Gr2 and Gr3 (represented in Fig. 5) are connected in their places.

I claim as mylinventionl. The combination of the reciprocating beam H', having punches I, with the beam H,

having upper dies, G?, and die-plate A, pr0- vided with lower dies, G, substantially as and for the purpose set forth.'

2. The combination of the eccentrics J J', 2o

having rods K', with the shaft Gand beam H', for giving reciprocating movements to the punches I, substantially as described.

3. The combination of the eyebolts c, having nuts e and jam-nuts e, with the beam H', 25

and connecting-rods K and K, as and for the purpose set forth.

WILLIAM WERTS.
